Title: Concentration and purification of polyunsaturated fatty acid esters by distillation-enzymatic transesterification coupling
Inventor: LE GOFFIC FRANCOIS
IPC: C07B61/00
Filed: 1999-05-31
Abstract: A process for producing highly concentrated preparations of polyunsaturated fatty acids and their esters from oils, especially fish oils, in which they occur mainly as their triglyceride esters. The process uses a combination of transesterification of the triglycerides with a lower alkyl alcohol or benzyl alcohol, molecular distillation and selective enzymatic transesterification with an alkoxy alcohol catalysed by lipases which desirably can be immobilized. The process permits the separation of the acids mixture usually encountered in the oils, and isolation of desired acids in high yields. Typical acids which can be obtained by means of this process are eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6).

Title: Inductor for a submersible pumping system
Inventor: PEARSON DONALD R
IPC: H01F27/06
Filed: 1999-06-07
Abstract: An inductor assembly is disclosed for protecting electronic circuitry in a downhole equipment string. The inductor assembly includes a plurality of modular inductors coupled to one another in series to provide the desired inductance. The modular inductors are supported by a support structure in a protective housing, such as in a common housing with the electronic circuitry. The inductor assembly is electrically isolated from the housing. The support structure may include insulative end members and rail members extending between the end members to which the inductors are secured. One or more insulative covers are provided around the inductors to further isolate the inductors from the housing. The inductor assembly dissipates energy in the event of certain failure modes of power supply circuitry or lines extending from the earth's surface. The inductor may be secured electrically between a neutral node in a Y-wound motor to prevent high voltage ac waveforms from damaging the electronic circuitry. Insulation of the inductors inhibits arcing with the housing, thereby inhibiting damage to the inductors or the electronic circuitry during such failure modes.

Patent CA-2278386-A1 (CA)
Inventor: BRAUN NORMAN L
IPC: F26B17/12
Filed: 1999-07-22
Abstract: A continuous flow particulate material dryer includes a base and a heating chamber extending upwards from a central location of the base for providing heated air to the dryer. A perforated inner wall structure extends upwardly from the base and surrounds the heating chamber. A perforated outer wall structure is spaced apart from the inner wall and extends upwardly from the base surrounding the inner wall. A main drying chamber is defined by the space between the inner and outer wall structures. A perforated partition separates the main drying chamber into an inner and an outer chamber. The partition restricts the flow of particulate material from the inner chamber and the outer chamber. An upward facing conical protrusion mounts above the heating chamber for dispersing the particulate matter evenly into both inner and outer chambers. A circular chamber having a rotatable auger therein is used to collect the particulate material from the base of the dryer. The auger includes ribbon flighting on an outermost portion for drawing particulate material from the outer chamber and full flighting on a remaining portion for drawing particulate material from the inner chamber. The full flighting draws the particulate material more quickly than the ribbon flighting, thus the particulate material flows through the inner chamber where the air is hotter at a faster rate than it flows through the outer chamber where the air is cooler to produce generally uniform drying.

Title: Hazard analysis critical control point (haccp) can opener
Inventor: BELLIS MARLA J
IPC: B67B7/46
Filed: 1999-11-19
Abstract: Disclosed is a safe and reliable method and apparatus for opening cylindrical metallic containers which cuts into the side of the cylindrical body of the can below the upper annular rim. The device of the present invention employs a specially adapted, angularly-positioned, tapered rotatable blade for performing the cutting operation. The use of a rotatable blade results in a clean non-jagged cut around the circumference of the container. The use of a rotatable, tapered blade to cut below the annular rim or seam of the container results in an inwardly-bent edge on the newly-cut lid having no sharp edges. This facilitates easy and worry free removal of the lid. In use, a can is placed in the device such that the knurled edge of an upper disc rests upon the top of the can. The rotatable side cutting blade is then moved such that it pierces the side of the can, just below the lip seal. The side cutting blade is locked into place, and the upper disc is rotated, thereby rotating the can. As this takes place, the rotatable side cutting blade cuts the top off the can.

Abstract: The present invention relates to a telecommunication device and method which converts pulses generated by rotary dial phones to DTMF signals, allowing the use of CTI applications regardless of the type of telephone set used by the caller or the type of the CO switch. Pulses are identified by the device's algorithm and converted into appropriate DTMF signals. This device connects across in parallel with all the telephone lines on the subscriber side at the CO that require monitoring to detect loop current. Pulse dialing as well as overdialing from a rotary phone is thereby detected and these pulses are converted into DTMF signals, suitable for extended services. The device can also determine time and date of the call, number dialed by the user and also the length of the call from the end of the initial dialing to the disconnection of the line.
